1 Claim.

'I'his invention relates to dumping buggies especially adapted for loading mine cars with ore obtained from mine rooms inaccessible to mine cars and has for the primary object the provision of a device of this character which will provide saving in time and labor and may be readily set up in a mine room, whereby the buggy may be loaded and then moved to the mine car by power derived from a power source and caused to assume a dumping position to deposit the load thereof directly into the mine car.

With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation showing a dumping buggy and its operating means.

Figure 2 is a top plan view illustrating the same.

Figure 3 is a perspective view showing a combined chock and cradle for the buggy.

Figure 4 is a fragmentary side elevation, partly in section, showing in detail the buggy assuming dumping position.

Referring in detail to the drawings, the numeral I indicates a mine comprising the usual main passage 2 in which travel mine cars 3 for the purpose of conveying to the surface of the ground ore taken from rooms 4 extending laterally from the main passage and inaccessible to the mine cars due to the dimensions of such room and also in many instances located in a plane other than the plane of the main passage, as clearly shown in the drawings. These rooms may extend for a considerable distance from the main passage necessitating the conveying of the ore from said rooms to the main passage. In order to easily, quickly and cheaply transfer this ore, a dumping buggy 5 is provided and made to operate on a track 8 and a combined chock and cradle I is located at the mouth of the room so that when the buggy arrives at a point adjacent the main passage it will assume a dumping position and deposit its load directly into the mine car 3.

The buggy 5 includes a body 8 supported by car Wheels 9 adapted to travel onv the track 6. One end of the body is closed by a removable tail gate I secured to and movable with arms II pivoted to the body 8 adjacent the other end thereof. Normally the arms II parallel the sides of the body positioning the tail gate to close the open end of the body. Projections I2 are secured to the body 8 and extend beyond the tail gate to engage with the chock when the buggy is moved into the combined chock and cradle.

The combined chock and cradle consists of a bed I3 on which the ltrack 6 terminates and secured to the bed are members I4 terminating at one end of the bed in upwardly and rearwardly inclined chock elements I to be engaged by the projections l2 of the buggy. Side panels I6 rise upwardly from the bed I3 and may be reinforced by a cross brace I'I and by uprights I8 to engage with the ceiling of the room 4. At the entrance end of the combined chock and cradle, the panels I6 are provided with diverging wings I 9. The

side panels I6 act as guides for the buggy during l5 its movements from dumping to non-dumping position.

In mines it is frequently necessary to ventilate the rooms 4 and a power source 28 is provided for driving a fan 2l acting to circulate air into the rooms 4. The power source may be employed for furnishing power for the operation of the buggy 5 and also for the movement of mine cars in the main passage relative to the rooms 4.

Drums 22 and 23 are suitably journaled in the mine opposite the room 4 and located adjacent the drum 22 is a drum 23. Gearing 24 connects the power source with the drum 23 or to a shaft 25 acting as a support for the drums 22 and 23, the latter being connected and disconnected to said shaft by clutches 26. The shaft 25 is also geared to a shaft 2'I on which the drum 23 is journaled. A clutch 28 connects and disconnects the drum 23 with the shaft 21. Brake mechanisms 29 are provided f or the drums heretofore mentioned.

Secured to and wound on the drums 22 and 23 are cables 38 and 3I. The cable 3I is secured to the tail gate Ill by a hook 32 fitting in an eye 33. The cable is secured to the opposite end of the body of the buggy t0 the tail gate in a similar manner after passing over a pulley 34 secured to a Wall of the room 4 and passing beneath the buggy. The drum 22 and the cable 30 are employed for drawing the buggy into the room 4 and the drum 23 and cable 3| are employed for drawing the buggy into the combined chock and cradle 1 and also for causing the buggy t0 assume dumping position, as shown in do-tted lines in Figure 1. When the projections I2 engage the chocks I5 and on further winding of the cable 3| on the 50 drum 23 and its free end is provided with a hook 36 which may be engaged with an end of the mine car so that on winding the cable 35 on the drum 23 the mine car will be caused to move in the main passage and relative to the room 4.

Having described the invention, I claim:

In a mining apparatus, a portable frame adapted to be secured in a xed position within a mine room entrance adjacent a loading passage and having spaced longitudinally extending members fashioned with angularly disposed end sections extending upwardly and inwardly towards the center of said frame and constituting chocks located at the ends of said members positioned adjacent said passage, track members secured Within said frame in parallelism with said first mentioned members and extending into a mine room, a buggy normally mounted on said track members and wheelable over the latter into and out of said frame, said buggy fashioned with a closed end and a discharge end having chock engaging projections extending therefrom, spaced arms embracing said buggy and having ends pivoted to said buggy adjacent the closed end thereof, a gate secured to said arms at the opposite ends for closing the discharge end of said buggy when the latter is in wheelable engagement with said track members, and power means connected to said gate and passing through said frame for wheeling said buggy into said frame in a manner whereby continued movement of said buggy by said power means toward said chocks eifects engagement of said projections with said chocks and pivots said buggy upwardly out of engagement with said track members and pivots said arms relative to said buggy to simultaneously move said gate to open position to allow the contents of said buggy to discharge through said discharge end of said buggy above said loading passage.
